Optical Coherence Tomography–Guided Transepithelial Phototherapeutic Keratectomy for the Treatment of Anterior Corneal Scarring – Corrected Proof
Purpose: To report the visual and anatomic outcomes of a novel technique for the management of anterior corneal scarring using optical coherence tomography (OCT)–guided transepithelial phototherapeutic keratectomy (transepithelial PTK).Design: Retrospective, consecutive case series.Methods: The charts of 22 patients with anterior corneal scarring associated with irregularities in the Bowman layer who had undergone transepithelial PTK according to a novel protocol were reviewed. The protocol consisted of a preoperative OCT-measured depth-of-treatment calculation, followed by a dual excimer laser treatment profile set to achieve the desired refractive outcome while eliminating or reducing corneal scarring. The primary outcomes were change in best spectacle-corrected visual (Read more...)
